The circumference of a 144-inch diameter circle is about 452.4 inches. (C = d x Pi).
The formula for calculating the area of a circle is 'pi r squared,' where 'r' represents the radius of the circle. A radius of a circle is, of course, half its diameter. Therefore, divide the diameter (24) by 2, then square it, then multiply that figure by pi. Twenty-four divided by two is twelve. Twelve squared is 144. So, multiply 144 by pi and 'Bob's your uncle.'
you take the diameter and divide it in half then you have the radius. Take the radius and multiply the radius by its self (radius squared) then multiply by 3.14 (pi) example: Diameter is 24 find the area. 24 divided by 2 is 12 12x12= 144 144x3.14= 452.16
The only shape that can do that is a circle.Circumference = 24.Diameter = 24/piRadius = 12/piArea = pi R2 = 144/pi = 45.837
If 12x12 is 144... There would be 144 tiles in a box right?
The circumference of a 144-inch diameter circle is about 452.4 inches. (C = d x Pi).
x2 + y2 = 144 = radius squared radius = sqrt (144) = 12 diameter = 2 x radius = 24
144(PI)
Area = pi*144 = 452.389 square cm
144 ft.That would be twice the radius.
72 The diameter is the full length from left to right and the radius is taken from a central point, in this cas at the 72 mark.
Use the formula area = pi times radius2 to get the area. The radius is half the diameter. A foot is 12 inches, a square foot is 144 square inches.Use the formula area = pi times radius2 to get the area. The radius is half the diameter.

Vol = 4/3*Ï€*r3 where r, the radius, is diameter/2 Vol = 1563457.6 cubic metres.
13 inches = 13/12 feetarea =pi(diameter)2 (1/4)= pi(13/12)2(1/4)= pi(169/144)(1/4)=pi(42.25/144)=.92175 square feet
(x + 2)2 + (y - 6)2 = 144

volume of a cylinder is h(pi)r2 or 144*24.5^2*pi or 271546 in3 or 30171 ft3 converting to Gal we get 225700 gal
